(svn r9082) -Codechange: [win32] Update VS2003 and VS2005 project files to use the same outpath, and build in UNICODE mode. When making a release it is probably better to make two binaries, one without UNICODE, the other with, guaranteeing full Win9x compatibility (UNICODE with MSLU also works, without it's even better).
-Remove: [os/2] Relic project file remains from watcom
